The smart intrauterine device (sIUD) is a contraceptive device to be inserted in the uterus with added functionality to measure metrics related to IUD placement and reproductive health. The design process began with researching current designs on the market and potential competitors through current and pending intellectual property. The factors that were considered for the design of the sIUD were the shape, contraception method, arm design, and sensor configuration. From the design factors potential users were surveyed via conjoint analysis to reveal that IUD shape and contraception method were the most influential factors. An abundance of designs were developed and evaluated using a Pugh matrix yielding the front running conceptual model. The sIUD has a novel shape design compared to the FDA approved “t-shaped” designs in the United States. There is a silicone elliptical sleeve manufactured from a bio-safe silicone shaped by resin printed mold system. The sleeve holds an SLA printed electronics housing cylinder where the electronics like sensors, microcontroller, and power components are stored and sealed. A monofilament thread loop is bonded to the inside of the electronics housing for manual IUD placement monitoring and removal of the device. The contraception method used by the device is copper. A web application was developed to allow users to record, view, and share their data from the sIUD. The application uses React and Node.JS frameworks and the database for user information is hosted on MongoDB Atlas.
